HAND-FIREARM.

Specification of Letters Patent.

Patented Get. i3, Mild.,

Application led February 20,1914. Serial No. 819,957.

. ejecting shells and reloading.

The object of the invention is to provide certain new and useful improvements in hand firearms oi' the type referred to Whereby the liring may be produced periodically on the user pressing the trigger or the firing may be rendered continuous until all or a desired number of cartridges have been fired.

In order to accomplish the desired result use is made of means connected with the locking andreleasing lever for locking and releasing the -iring pin, and controlled by one of the rollers at the toggle joint of the toggle levers connected with the breech block.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specilication, in

which similar characters of reference indi-l cate corresponding parts in all the views.

Figure l is a side elevation, partly in section, of an arm of the Luger type and provided with the improvement; Fig. 2 is a plan view of the same, parts being in section; Fig. 3 is an enlarged face view of the attachment on the locking and releasing lever for` the ring pin; Fig. 4; is a plan view ot the same; and Fig. 5 is a perspective view of the connection between the trigger and the locking and releasing lever of the Afiring pin.

In the arm of the Luger type shown in Figs. l and 2, the breech block A. is mounted to slide lengthwise in suitable gnideways 'arranged in the framework B and the said breech block is pivotally connected with the knee or toggle levers C, C provided at the joint C2 with rollers D, D adapted to travel up and down on the cam faces E of the butt piece E forming part of the framework B. The roller D is adapted to engage a cam face F on the rea-r 'free end of a spring plate F adjustably secured on the outer side of the locking and releasing lever G controlled by the trigger ll (see Fig. 5), and adapted to engage a lug l projectirig transversely from the firing pin (not shown).

The spring plate F is provided with longitudinally extending slots F2, F3, of which the slot'F2 is engaged by a clamping screw J screwing in the locking` and releasing lever (l, and the slot F3 is engaged by a stud K held on the said lever G. On loosening the clamping screw J the spring plate F may Vbe moved forwardly into the inactive position shown in Figs. 1, 2, 3 and 4, and when this position is reached the screw J is screwedv up to fasten the spring plate F in position on the lever G., lVheu the plate F is in this position its cam face F is out` of the path of the roller l) and consequently the pistol can only be .fired on pressing the trigger H to cause the lever 0 to release the lug I of the firing pin. i

It is understood that the locking and releasing lever Gr is provided with the usual notch G engaging the fulcrum L for the lever G to swing on, and the said lever is also provided with the usual shoulder G2 adapted to engage the lug l to hold the liring pin in locked position. The locking and releasing lever is normally held against outward movement by the free end N of the spring-pressed lockingr lever N fulcrumed at N2 in the handle 0 and having a hand plate N 3 normally projecting on the back of the handle O. The magazine l for the cartridges is removably held in thc handle O in the usual manner.

lt is also understood that in firearms oi the Luger type the breech block is moved rearwardly by the recoil and during this movement the shell is extracted and the main spring is placed under tension so that after the force of the recoil is spent the main spring returns the breech block to closed position, but during the time the breech block is in open position a cartridge is ied by the magazine into position for the breech block to push this cartridge into the barrel.

lhen it is desir-'ed` to successively fire the pistol, the operator loosens thc screw ld' and then slides the spring plate F rearwardly into the position shown in dotted lines in `Fig. Il. The spring plate F is secured in this adjusted. position by screwing up the screw J. When the spring plate F is in this rearmost active position it extends into the path of the roller l) and consequently when the breech block A is moved into closing position the roller D engages the eam face F and bends the free end of the spring plate F outward thus placing the spring plate'F un der tension, as the lever G is held against outward movement by the end N of the and when this takes place the spring arm F on account of being under tension swings the lever G outward whereby the lug I and consequently the tiring pin is released and the pistol is tired they same as if the trigger H had been pressed. The firing is automatically` repeated as long as the user keeps the hand plate N3 pressed. After the first shot is fired the breech block is moved rearyWardly by the recoil and the roller D disengages the free end oi the spring arm F to allow the lever G to be reengaged by the lug ul of the tiring pin, but when the toggle 'levers return and the breech block moves forward into closed position, the roller D again engages the free end o'E the spring arm F thus swinging the lever G outward to release the firing pin for tiring the second shot. The above described operation is repeatedat'ter tiring a shot and as long as the hand-piece N3 is kept pressed, but the tiring can e stopped on the user releasing the hand-piece N3 to allow the free end N of the lever N to rengage the lever G and prevent its outward movement by the action of the spring arm F. It is further understood that when the toggle levers C, C straighten out, the? barrel and the breech block again act one piece while the lug l ot' the tiring pin engages the shoulder G2 to hold the percussion spring of the .tiring pin in pressed position until the lug is released on imparting a swinging motion to the released lever G either by pressing the trigger H or by the roller D acting on the spring plate F, as above explained. rl`he spring arm F and the means for slidingly attaching it to the lever G are the only new parts added to the r pistol of the type relerred to.

Having thus described our invention, we claim as new and .desireto secure by Letters Patent: i

l. In a firearm of the type described, the combination of a locking and releasing lever for locking and releasing the firing pin, a breech having a toggle joint provided with a roller, and means connected with the said locking and releasing lever and controlled by the said roller for automatically unloele ing the firing pin from the breech.

f2. A firearm of the type described provided with a member adjustably secured on the locking and releasing lever for the firing pin, the said member in one position being out of the path of one of the rollers of the breech and the said member in another position being in the path of the saidqoller to cause the latter to impart movement to the said member and the said locking lever to automatically unlock the firing pin.

3. A firearm ot' the type described provided vvith a plate, and means for adjustably securing the said'plate 'to the locking and releasing lever ot' the firing pin, the said plate projecting rearwardly bevond the rear end of the said locking and releasing lever, and the rear end of the said plate having a cam face adapted to be engaged by one of thel rollers of the breech to automatically actuate the said locking and releasing lever -to release the tiring pin.

In testimony whereof we have signed our names to this specification in tlie,presence of two subscribing witnesses.
